Step-by-step explanation:
Area of a circle = pi x square of radius = 30.190 ft
Answer:
Step-by-step explanation:
x+y = 60
x-y = 8
------------
2x = 68
x = 34
y = 60-x = 26
Answer:
y=25
Step-by-step explanation:
10*2=20
20+5=25
Answer:

Step-by-step explanation:
<u>Key skills needed: Exponent multiplication, Multiplication</u>
1) We have the expression --> 
2) We have to simplify this (the parentheses mean multiplication)
The easiest thing to do is: Multiply 4 and 6 --> 4 x 6 = 24.
3) With the step above, the expression now would be
.
We now have to do
× 
For this we have to use this exponent rule -->
×
=
.
4) This means that
×
=
5) So the simplified expression would be -->
